WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wi-fi and PoE at same time. Once you connect the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the set up environment and investigate which functions you want to attain.
Wireless or PoE, which is best? As a mature technician who may have four years in video recording surveillance industry, my response to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transfer data through cordless signal (2.4GHz UHF music group, 5GHz SHF group).
Obviously, once the IP camera supports WiFi, the camera can hook up your router without needing hardwired connection. WiFi can allow IP camera become portable, this is the advantage of WiFi.
But there are two disadvantages on WiFi, that are; every gadgets require power, that means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP cameras are able to operate with power packs.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far will Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including vitality rate of Wireless device, environment (interior or outdoor) and much more.
Typically, a home/office router (TP-Link) provides WiFi coverage grows to up to 10 meters inside.
When Wi-fi devices will work outdoor without barrier, the transmitting distance will be much much.
To extend the Wi-fi coverage or distance, you can mount WiFi gain access to point. Such an access point (or hotspot) has a variety around 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over solo Ethernet wire (Kitten5/6) is the primary feature of PoE technology.
So long as your IP camera supports PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP surveillance cameras support plug-and-play assembly, which greatly reduced the unit installation procedures, and eliminate the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum vitality rate is to 15.4 W of DC electricity (lowest 44V DC and 350mA) to each device.
In order to provide power for high vitality utilization devices, the IEEE association made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Downsides AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet cable television, no need extra electricity cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable television, there is absolutely no signal disturbance, no indication jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is essential component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive when compared to a traditional network swap, which increased just a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for Wireless IP camera.
Ensuring the Wireless IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is preferred. PoE is much reliable than Wi-fi in conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to deal with, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of security market, I found that WiFi IP surveillance cameras are widely used for non-professional inside security, and PoE IP cameras are installed for outdoor surveillance system. But if you select WiFi IP Camera please read article below.
So how do you really determine which wireless IP camera suits your preferences?
Firstly, establish what you need. Many purchasers often don't really know which type of cordless IP camera suites and would fulfill their needs. As a result, they get sucked into buying cellular IP cams that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or dazzling); what detail of data do you want to catch? (HD images with or without audio) and most importantly, what is your budget?
Secondly, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Of course, this feature will be based upon the surroundings where you intend to use the camera.
A wide pan and tilt range is never a negative thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Ensure that you check the sort of zooming potential, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never fail to find one with optical zoom.
Fourth, test the gear before purchase.
This is vital, in particular when you are buying from your local electronic store.
Always request for a test setup as this will enable you to determine the picture quality of the camera.
Furthermore, it will give you an opportunity to learn how to set up the equipment in an effective manner to make certain you get the best image and sound quality.
